Unfortunately, we could not automatically migrate the data from the old boards. All we can do is manually copy some things over and then leave the old boards as a read-only archive. And we will likely be doing that for quite some time, even though we do not have any intention of moving all the old threads over, or even a majority of them.
So:
• Do know we'll be moving some of those threads over on and off for at least a couple of weeks. It might be kind of like having the movers still coming back and forth into your place when you're now living there, which is super-annoying, so we'll be as inobtrusive with that as we can be.
• If you have threads or posts from those boards you'd like to see moved that we haven't yet, by all means, let us know! If you just post the URL for those threads in this thread here, we'll have a look and get the threads you loved moved!
Don't forget: if you were a user at our old boards, and let us know your handle there, we're happy to get your account set up so you can come right out of the newbie queue. The place to do that is here: http://scarleteen.com/bb/viewtopic.php?f=21&t=23
